MARKING ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters raters No. '782,381, dated February 14, 1905.

7 Application filed November 10, 1904. Serial No. 232,194.

To all whom, it may concern:

.Be it known that 1, JOHN FRANoIs CALLA- I-IAN, a citizen of the United States, residing at Sac City, in the county of Sac and State of Iowa, have invented a new and useful Marking Attachment for Corn-Planters, of which the following is a specification.

This invention relates to marking attachments for corn-planters; and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability,and general efliciency.

With these ends in view the invention consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being however understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes and alteration may be made within the scope of the invention and without departing from the spirit or sacrificing the efficiency of the same.

In said drawings, Figure 1 is a sectional elevation of a conventional form of check-row corn-planter having the invention applied thereto. Fig. 2 is a top plan view of the same on a reduced scale. Fig. 3 is asectional detail view taken through the marker-stafl and showing the means for connecting the same with the lifting element. Fig. 4 is a detail view in elevation, illustrating a slight modification; and Fig. 5 is a perspective detail view of said modification.

foot-lever 7 and a manually-operable adjustinghand-lever 8, having a spring-actuated dog or catch 9, adapted to engage a rack-segment a bracket 13, extending rearwardly from the tongue 14, which latter is supported upon the runner-frame. The link 12 is in the nature of a bolt which extends through the bracket 13, secured to tongue 14, and upon said bolt is coiled a spring 15, whereby a flexible support for the rear end of the tongue is provided.

Upon the main frame is mounted a seat-supporting bar 16, serving in part to support the seat 17 Pivotally connected with the seatbar 16 is a lever 18 with which is adjustably connected a link 19, having a slot 20, which slidably engages a'bolt 23, which also serves for the attachment of a treadle 24.

Pivotally connected with the rear side of the main frame is the marker-staff 25, which is provided at its outer extremity with a scribe 26, adapted to engage the ground and to make a continuous mark or furrow therein, said scribe being double-pointed, so that it will engage the ground in any position that may be occupied by the marker-staff when the latter is in position for operation.

27 is an eyebolt extending transversely through the marker-stafl and through a pair of flanged clamping-plates 28, which embrace opposite sides of the staff and which are firmly secured therein by means of the eyebolt 2.7 and the nut 29 upon said eyebolt. The point of the marker-staff which is weakened by the perforation for the passage of the eyebolt 27 will be reinforced by the clamping-plates 28 and danger of breakage at this point will consequently be avoided. The eyebolt 27 serves for the attachment of one end of a rope, chain, or similar flexible connecting element 30, the other end of which is connected with the free end a rearwardly-extending bracket 33, carrying ployed, said rod serving to connect the lever 18 with a bell-crank or elbow member 22, which is pivotally connected by the bolt 23 with the foot-lever 7.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. the scribe at the end of the marker-staff will indent the ground and form a furrow to guide the operator on the return trip. When the machine is to be turned at the end of the field, the operator after releasing the catch 9 from the segment-rack 10 operates the hand and foot-levers to rock the shaft 6 for the purpose of tilting the runner-frame. By the same operation the lever 18 is operated by means of the link connecting it with the foot-lever, and the free end of the marker-stafi will be thrown to an approximately vertical position, where it is temporarily retained while the machine is being turned by permitting the catch 9 to engage the rack-segment. After turning the machine the catch of the hand-lever is again released, and the hand and foot levers are operated to restore the runner-frame to its operative position, the free end of the lever 18 being simultaneously elevated, thus permitting the marker-staff to drop, said markerstaif being pushed in the proper direction by the hand of the driver.

This device, as will be readily seen, is extremely simple and free from all unnecessary complications. It may at a small expense be applied to any ordinary form of corn-planter, and the marking device is operated by the same means which are provided for the purpose of tilting the runner-frame when the machine is being turned at the end of the field.

If during the progress of the machine over the field it becomes desirable to elevate the marker from contact with the ground without tilting the runner-frame, this may be easily accomplished by the operator placing his foot upon and depressing the lever 18, whereby the marker is directly actuated. The slot 20 in the link 19, or in the modified construction illustrated in Figs. 4 and 5 the elbow member 22, will permit this operation, to be performed without disturbing the position of the lever 7.

Having thus described the invention, what is claimed is 1. In acorn-planter, a marker-stafl connected pivotally with the rear end of the main frame, a stationary support, a lever pivoted to said support, a flexible element connecting the free end of said lever with the markerstaif, a guide-pulley for said flexible element When the machine is in operation,

supported above the free end of the lever, and operating means for the latter including a rock-shaft, a lever connected with said rockshaft, and a link connecting said lever adj ustably with the lever having connection with the marker-staff.

2. In a cornplanter, a marker-staff connected pivotally with the rear end of the main frame, a seat-supporting bar, a lever connected pivotally with said bar, a flexible element connecting the free end of said lever with the marker-staff, a guide-pulley for said flexible element supported by the seat, and operating means including a rock-shaft supported upon the main frame, a lever connected with said rock-shaft, and a link connecting the latter lever with the lever fulcrumed upon the seatsupporting bar.

3. In a corn-planter, a main frame, a runner-frame having a tongue supported thereon, a rock-shaft supported upon the main frame, a foot-lever connected with said rock-shaft, connecting means between the front end of the foot-lever and the rear end of the tongue, a hand-lever upon the rock-shaft having a catch, a segment-rack engaged by said catch, a marker-staff connected pivotally with the rear end of the main frame, a seat-support upon the main frame, a lever pivoted upon said support, a flexible element connecting the free end of said lever with the marker-staff, a guide for said flexible element supported by the seat; and a link connecting the lever pivoted upon the seat-support with the rear end of the foot-lever.

4:. In a corn-planter, a marker-stafl connected pivotally with the rear end of the main frame, a seat-support upon the main frame, a lever pivoted upon said seat-support, a link pivoted at the rear end of said lever, a suitably-guided flexible element connecting said link with the marker-staff, a rock-shaft supported upon the main frame, a foot-lever upon said rock-shaft, an elbow-lever upon said footlever having a laterally-extending bolt, and a link connected pivotally with the lever pivoted upon the seat-support and with the laterallyextending bolt of the elbow member.

5. In a corn-planter, amarker-staif connected pivotally with the rear end of the main frame, flanged clamping-plates engaging opposite sides of said marker-stafl, an eyebolt extending through said clamping-plates and staff, a tightening-nut upon said bolt. a seatsupport upon the main frame, a lever pivoted upon said seat-support, a link pivoted at the free end of said lever, a suitably-guided flexible element connecting said link with the eyebolt upon the marker staff, and operating means including a foot-lever which serves also to efiect the tilting of the runner-frame, and a link connecting said foot-lever with the lever pivoted upon the seat-support.

6. In a corn-planter, a marker-staff connected pivotally with the rear end of the main means including a rock-shaft supported upon the main frame. a lever connected with said rock-shaft, and a yieldalole connection between I 5 said lever and the lever supported upon the seat-bar.

In testimony that I claim the foregoing as my oWn I have hereto aflixed' my signature in the presence of two Witnesses.
